TRANSMITTING MOTION.

Specification of Letters Patent.

Patented July 16, 1907.

Application filed September 27,1905. Serial No. 280,315.

To all whom it may concern:

Be it lznown that I, JOHN F. PAGENDARM, a citizen of the United Statesof America, and a resident of San Francisco, in the county of SanFrancisco and State of California, have invented certain new and usefullmprovements in Transmitting Motion, of which the following is aspecification.

The present invention relates to a system of transmitting motion betweenpoints indirect or remote from each other by means of fluid pressure,and has for its object to provide a simple and efficient structuralformation and combination of parts, whereby the motion imparted to motorat a central point or station is .transmitted in a certain and positivemanner to similar motors at remote points, and with which a simultaneousor serial action upon the receiving motors at such different remotepoints is regulated and controlled in a ready and convenient manner bythe operator at the central point, all as will hereinafter more fullyappear and be more particularly pointed out in the claims.

In the accompanying drawingsz-Figure l is a vertical sectional elevationon line xx, Fig. 3 of the driving hydraulic motor of the system. Fig. 2is a similar view of the driven hydraulic motor of the system, and Whichin connection with the aforesaid driving hydraulic motor illustrates theprimary form of the pres ent system. Fig. 3 is a horizontal section online .t x Fig. l, of the hydraulic motor. Fig. 4 is a side eleva tionillustrating the combination of a driving motor and a multiplecontrolling valve in a complex form of the apparatus adapted to transmitmotion to a number of remote points or stations. Fig. 5 is a detailvertical section on line x x Fig. 8, of the said controlling valve. Fig.6 is a fragmentary view similar to Fig. 5, illustrating a pair of theradial passages of the controlling valve connected together by theby-pass, of the valve plug or head controlling said radial passages.Fig. 7 is a side elevation of said controlling valve. Fig. 8 is a detailvertical section on line x x Fig. 5, of said controlling valve.

Similar numerals of reference indicate like parts in the several views.

Referring tothe drawings :1 is the driving hydraulic motor arranged atthe central or controlling point or station of the system; 2 is thedriven hydraulic motor arranged at one of the remote points or stationsof the system, and 3 are a pair of fluid transmission pipes leading awayfrom the opposed ends of the driving motor, and adapted for connectionto the opposed ends of the driven motor, or series of driven motors, ashereinafter more fully set forth, and so that with the manual operationof the driving motor in one or the other direction, will cause acorresponding movement of the driven motor or motors.

In the simple form of the present system, employing but a single drivenmotor, the pair of fluid transmission pipes 3, will extend in a directmanner between the driving and the driven motor; while in a more complexform of the present system employing a number of driven motors locatedat points remote from the central station as well as from each other,the said fluid transmission pipes 3, will be connected to a controllingvalve 5 as illustrated in Fig. 4; and such controlling valve will inturn be connected by a number of pairs of branch fluid transmissionpipes 4,individual to a similar number of the driven motors.

The hydraulic motors employed in the present system are of the doubleacting type,and with a view to a compact and powerful arrangement ofparts, such motors are preferably of the construction shown in Figs. 1,2 and 3, of the drawings, and comprise a structural formation andcombination of parts as follows 6 is the motor casing preferably of asemi-cylindrical form, open at one side, as shown in Fig. 1.

7 is a marginal end flange onsaid casing, affording convenient means forsecuring the motor in a fixed position.

8 is a base plate secured to the open side of the casing 6, and adaptedto carry the hereinafter described stationary motor pistons.

9 are a pair of stationary pistons, cast or otherwise attached to thebase plate 8, in the opposed relation shown; such pistons are of acurved or segmental form and are arranged in substantially concentricrelation to the pivot axis of the semi-rotary motor cylindershereinafter described.

10 and 11 are the induction-eduction ports or ducts of the motor, formedin the base plateS and pistons 9, as shown, and having connection at theouter ends with a pair of the fluid transmission pipes 3 or 4,aforesaid.

12 are piston heads, preferably of the cup form shown, secured to thefree ends of the pistons.

13 is the semi-rotary motor shaft journaled in the easing 6 and providedwith pairs of radial heads 14, and arms 15, adapted to carry the pair ofcylinders of the motor.

16 are the motor cylinders of a curved or segmental form carried by theradial heads and arms aforesaid, in concentric relation to the axis ofthe motor shaft 13, aforesaid.

In the present construction one end of each cylinder is closed by a head14 while the other end is left open to receive the piston and its pistonhead, and such open end is supported in place by one of the radial arms15, which for this purpose is made of a ring shape adapted to fit theexterior of the cylinder.

In the present construction the respective pistons and cylinders inaddition to having an opposed relation as above described, are arrangedto one side or the other, as shown in Fig. 3, so that their free endsmay lap past each other to aii'ord a very compact arrangement 01' theparts.

The multiple controlling valve heretofore referred to will in thepreierred form of the present invention comprise an arrangement of partsas follows 17 are a pair of annular distributing chambers formed in thebody oi the valve, in separated and parallel relation.

18 are a pair oi radial passages having individual communir'tation attheir inner ends with the distributing chambers 17, and at their outerends with the pair of fluid transmission pipes 3 oi the driving motor l.01 the system.

It 9 are a series 01 pairs of radial passages formed in the body oi thevalve, and extending outwardly from the distributing chambers 17, withtheir outer ends adapted for connection with a series of pairs of fluidtransmission pipes 4, having connection with the series of driven motors2, oi the system.

20 are a series of transverse orifices in the body oi the valve inintersecting relation to the series of pairs of radial passages 19; suchtransverse orifices are prel'erably made tapering and constitute seatsfor a series of individual plug valves herein-alter described.

21 are the series of individual plug valves, above reierred to, providedat one end with an operating handle 22, and intermediate of their lengthwith pairs 01' transverse passages 23, in line with the radial passages]9 above described.

24 is a longitudinal recess or passage formed in the periphery of eachplug valve 21, in angular relation to the transverse passages 23,thereof; each longitudinal passage has a length great enough to span apair of the radial passages 19, controlled by said plug valve, so thatwhen in register with said radial passages 19, the longitudinal passage24 will term a by-pass between the pair oi radial passages, asillustrated in Fig. 6, for the purpose hereinafter set iorth.

25 is a lever or handle, secured to the shalt 13, of the driving motorfor the convenient manual actuation of the same.

The operation of the complex and prei'erred form of the presentinvention, is as iollows:-With the appa ratus set up and the motorcylinders, pipes, etc. filled with a suitable fluid, a movement of theoperating handle 25 of the driving motor 1 in one or the other directionwill cause one of the cylinders 16 to move over its piston and expel thefluid i'rom such cylinder through a pipe 3 into the distributing chamber17 of the controlling valve 5, and from thence through one or more oithe radial passages 19 and distributing pipes 4 into a correspondingcylinder or cylinders of a driven motor or motors 2, to efi'ect anoperation of the same in one direction. Such movement of the operatinghandle 25 will cause a simultaneous travel 01' the companion cylinder ofthe driving motor 1 from of]? its piston, to draw the fluid into suchcylinder from the corresponding cylinder or cylinders oi the drivenmotor or motors 2, through the connecting set of pipes 4', distributingchamber 17 and pipe 3. With a movement oi the operating handle 25 in acontrary direction, a like position of the companion parts, lastreferred to,

takes place, so that a positive motion in both directions is assured ina practical operation of the apparatus. By an adjustment ()1 theindividual valve heads 2]. to a position in which their pairs 01'transverse ports or passages 23 form open communications between thepairs oi radial passages 19 and the pairs oi annular distributingpassages 17, the parts are in position for a normal action of the entireapparatus. By an adjustment of any one of the individual valves 21 tothe position illustrated in Figs. 6 and 8, the communication between thedriving motor and the particular driven motor is closed, and the bypass24 connects the particular pair oi radial passages 19 so that suchdriven motor can be independently adjusted as required. By an adjustmentof any one of the individual valves 21 to a position in which the pairof transverse pas 23 and by-pass 24 are out oi register with the pairsol' radial passages 19, the particular driven motor is cut off fromoperation by the main driving motor, and locked in the position to whichit had been previously adjusted.

The present invention is applicable to a great many uses in thepractical arts, and among the many may be mentioned, the operation andcontrol from a central station of a number 01' remote railway switches.

-gates or analogous appliances, also the control of a series of doors,and the like, i'rom a central ollicc or station of a building or plant.
